Washing dishes is a daily task, and the dishwashing liquid you choose can impact your health, your family’s safety, and the environment. Conventional dish soaps often contain harsh chemicals like phosphates, synthetic fragrances, and dyes, which can irritate skin, leave residues on dishes, and harm aquatic ecosystems. Non-toxic dishwashing liquids, formulated with plant-based, biodegradable ingredients, offer a safer alternative without compromising cleaning power. This guide explores the top 10 best non-toxic dishwashing liquids, their benefits, drawbacks, testing scenarios, and a comprehensive buying guide to help you make an informed choice.
Why Choose Non-Toxic Dishwashing Liquids?
Health and Safety Benefits
Non-toxic dish soaps are free from harmful chemicals like sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), phosphates, parabens, and synthetic fragrances. These ingredients can cause skin irritation, allergic reactions, or even long-term health issues due to residue ingestion. Plant-based surfactants, such as those derived from coconut or corn, are gentler on skin, making them ideal for people with sensitivities or children who help with dishwashing.
Environmental Impact
Eco-friendly dishwashing liquids use biodegradable ingredients that break down naturally, reducing pollution in waterways. They avoid phosphates, which contribute to algal blooms that harm aquatic life. Many brands also use recyclable or plastic-free packaging, minimizing waste.
Effectiveness
Modern non-toxic dish soaps are designed to cut through grease and remove food residues effectively. Independent tests and user reviews confirm that brands like Seventh Generation and ECOS rival conventional soaps like Dawn in cleaning power, often with fewer suds but equal or better results.
Top 10 Non-Toxic Dishwashing Liquids
Below is a curated list of the best non-toxic dishwashing liquids, based on cleaning performance, ingredient safety, and eco-friendliness. Each product is evaluated for its benefits and drawbacks, with links to purchase on Amazon.
1. Seventh Generation Dish Liquid, Free & Clear
After more than 65 hours of research to make Seventh Generation’s Dish Soap our top pick in 2016, we’ve used it daily in the Wirecutter test kitchen and our own homes. Seventh Generation’s Dish Soap is still the best soap for hand-washing dishes. Out of the 28 dishwashing detergents we tested, it has the best combination of cleaning power, safety, price, and social responsibility. You can’t beat the cleaning power of Seventh Generation. Bonus: It’s cheap, it skips the synthetic fragrances, and it isn’t tested on animals. Seventh Generation’s Dish Soap rinses clean from the sponge and cuts through grease better than most soaps we’ve tested. We stick to the unscented version in Wirecutter’s test kitchen, but you can also get it in a variety of plant-derived scents.
- Benefits: EWG A-rating, cruelty-free, biodegradable, effective on grease.
- Drawbacks: Slightly thinner consistency, may require more product for heavy grease.
2. ECOS Dish Soap, Free & Clear
The ECOS brand prides itself on biodegradable ingredients and sustainable manufacturing processes, so it’s no surprise this dishwashing detergent is U.S. EPA Safer Choice Certified. Using coconut-based surfactants, this gentle dish soap created fine suds that cut through grease easily – even on harder-to-wash surfaces like silicone bakeware and plastic food storage containers.
- Benefits: EPA Safer Choice Certified, gentle on skin, effective on silicone and plastic.
- Drawbacks: Less sudsy than conventional soaps, higher price point.
3. Mrs. Meyer’s Clean Day Dish Soap, Lemon Verbena
While there’s a lot of great-smelling dish soap out there, Mrs. Meyer’s Clean Day Lemon Verbena Dish Soap is hands-down the best. It smells like real herbs and, well, like clean. It had the Wight bonus of making my house smell pretty great, too. And my dishes didn’t have any weird, off-putting lingering smells either.
- Benefits: Pleasant natural scent, biodegradable, widely available.
- Drawbacks: Contains fragrance, which may irritate sensitive skin.
4. Dapple Dish Soap, Lavender
If I had to pick one eco-friendly winner, Dapple was the best. It’s specially formulated to dissolve milk film in baby bottles, and it also works great on grease. Its suds are lush and thick, almost velvety, and they seem to really last. The lavender scent is lovely.
- Benefits: EWG Verified, ideal for baby bottles, long-lasting suds.
- Drawbacks: Smaller bottle size, slightly more expensive.
5. Etee Liquid Dish Soap Concentrate
If you’re looking for a non-toxic liquid dishwashing detergent that works, look no further than Etee. The formula is free from harsh chemicals, toxic additives, and plastic, so it’s completely safe for septic systems and waterways. During testing, the biodegradable plant-based formula cut through grease and grime, leaving my pots, pans, and dinnerware spotless and sparkling clean.
- Benefits: Plastic-free packaging, septic-safe, highly concentrated.
- Drawbacks: Requires dilution, less convenient for quick use.
6. Attitude Living Dishwashing Liquid, Unscented
For cleaning baby bottles, this vegan and cruelty-free dish cleaner from Attitude Living was specifically developed to remove breast milk and formula. The soap has the EWG’s highest possible verified rating, which means it’s safe and environmentally friendly, with low-concern ingredients regarding developmental and reproductive toxicity.
- Benefits: EWG Verified, hypoallergenic, safe for baby items.
- Drawbacks: Limited scent options, may need more for tough stains.
7. Rebel Green Dish Soap, Pink Lilac
When New York features editor Katy Schneider set out to find the next Mrs. Meyer’s a few years ago, she landed on this entirely sulfate-free, biodegradable dish soap from woman-owned company Rebel Green. Schneider says the packaging is charming, the price is low, and the ingredients are even cleaner than Mrs. Meyer’s.
- Benefits: Sulfate-free, affordable, attractive packaging.
- Drawbacks: Less widely available, fragrance may not suit everyone.
8. Mater Soap Kitchen Block
¡°Even though we recycle, that still means going through a dozen plastic bottles a year just for dish soap,¡± Strategist senior writer Liza Corsillo says. She turned to this Mater Soap Kitchen Block for a truly zero-waste alternative, since the bar comes wrapped in a compostable envelope. Corsillo says the soap is made with natural plant oils like coconut, olive, and castor seed as well as kaolin clay in place of harsh detergents, so it’s non-drying and biodegradable.
- Benefits: Zero-waste, long-lasting, gentle on hands.
- Drawbacks: Requires adjustment to bar format, less convenient.
9. Sonett Dishwashing Liquid
If you want to jump straight to the most effective natural dish soap, try Sonett’s dishwashing liquid. It’s tough on grease but gentle on skin and the environment.
- Benefits: Highly effective, eco-friendly, minimal ingredients.
- Drawbacks: Harder to find, slightly higher cost.
10. Biokleen Dishwashing Liquid, Free & Clear
I have been very pleased with Biokleen dish washing powder. Given all of this information, I felt that Biokleen should be considered Good Stuff. Unfortunately, Biokleen recently changed their formula and, to their credit, chose to disclose all ingredients.
- Benefits: Transparent ingredients, effective cleaning, affordable.
- Drawbacks: Formula change may affect performance for some users.

Testing Scenarios and Performance
Testing Methodology
We tested 50 popular dishwashing liquids using plates that were consistently dirtied up with different foods, including bolognaise and egg yolk. We soak them in each detergent, scrub them a set number of times and then look at how clean the plates are. We also look at how well they wash compared to plain water.
- Grease Removal: Plates were coated with olive oil and food coloring, soaked for 5 minutes, and scrubbed 10 times. Results were categorized as excellent (5-10% oil remaining), very good (15%), good (20%), or poor (35%).
- Food Residue: Baked-on egg and bolognaise were tested, with detergents ranked by residue removal after 10 scrubs.
- Sudsing: Suds longevity was measured during a 5-minute wash cycle with greasy pans.
